Celica Forums General Discussion Engine and Performance Turbo Help

Well the GT has iron coast cylinders, the GTS has "treated" aluminium cylinder walls. (we call nikacil)We found no problems with the GT, but more with the GTS. The GTS engine is a nice engine as it is, but when you want to upgrade it... ,it is just sensitive. You can not trust the alu walls anymore. Also the cylinder walls are very thin on the GTS. So sleeving it is a good idea.

I have been running 2+,3 years on 14+ psi. I have internals from the very begining. I started costum 10:1 wiseco pistons. Then changed to 8,8:1. All my problems I met, is that I was forcing the limits to KNOW the limits.
I do affraid of rotary engines, as I do not know enough about them. Also as I know hard to replace just parts in it.

However I do think st2 cars are faaar enough for ppl. I try to tell ppl not to start straight st2 or st3 ( it is against sales, but still).Pushing the limits are only suggested to ppl who have good technical background!! There are actually only 3 carst with st3 kits. Me, Soceur (c2powergts) and Smaay with a SF costum kit and our tranny.

Against sales but its still better for the reputation of the company which in turn probably helps sales.

I would hate to put something on the market, have some n00b that has money buy it, install it, blow somethin up and come back to me and be like HEY, THIS BLEW UP MY ENGINE, YOU SCREWED ME. then go talk shit on forums.

I agree with PhatManRX7...that would suck. Hey Gas, quick question...what was the limit that you reached when you blew your tranny apart and some of the other stuff? And I read on another post about cams...i shouldn't get aftermarket cams yet until you test them?

Don't worry Gas I'll still go to Stage 3, I'll start at 8psi and then when i get used to the power I'll gradually boost up I'll boost up past 14 when i have more than one car..you convinced me That sound ok?

I braked the tranny at 17psi in the 3rd gear. 1st spin 2nd spin 3rd a bit spin then grip and brake. Well I ordered my cams as well so needs a little time and will post my expirience.
Do it step by step man, you will not regret it

Its not that I am affraid that an st2 or 3 not ok, just ppl really don`t know how much power the st1 allready does when they ride it. Dynos show nothing compared to a ride. It is also a big investment. This is a light car and boosting makes it feel so stronger.

sweet thanks man...at 17psi? oh crap hehe..so i shouldn't really boost about 14psi since i could break the tranny thats cool, i will have to wait till i get a second vehicle can you check this out for me, are these the right 6speed tranny shifter cables i need? i was going to go to junk yard to search for a dead celica but i posted here first. thanks man.

Here is that link:

Shifter Cables and housing make it a 6speed right? So i should get a knob right? lol..ill have a six speed then after the install of the cables and housing?

so..how much is the hardened tranny?

a crap load of money...with everything in it including LSD..i belive it is around $3600

well TRDOTC, you'll have a 6-speed when you have the gears inside. it may be easier to acquire a 6-speed out of a euro GT.

kk, figured once they were on lol, not just cause i have them j/p...thanks i was thinking of that but if i can get the shifter cables, knob and housing from a junk yard cheap, it would be a lot less then 1k, we will see when i can find one. Thanks for your help man. Now have to find out if those in the link i provided are the cables to make sure. he wants 100 shipped but want to make sure not much miles are on them..i only have 17k on my car

I dont think you need the cables at all.
could you also look for a cheap 5speed tranny? we want to have a look, if is it similar like the 6sp.

k cool, i will, i have a 5 speed I'll look around for pics if i can first.

whats the avg. 1/4 time on one of these stg 2 and stg 3 kitted celis?

Its a shame but we do not have any racer cosumers. So no clue what could be done with a good driver.

What? are you seirous? someone has to have it. Interesting, people drop all this money and they dont even wanna play with their toys. The first thing i do after i break in my motor is take it to get dyno tuned. and then to the track see what this puppy can do.

don't worry gas, just gimme a free kit and i'll take it to the track for ya

don't worry gas, once i get it, i will dyno it for sure It is rediculous that nobody has done that yet!

geeyeah. im thinking of going with the st2 turbo kit but i have an automatic transmmission. is the kit even worth getting if i had an automatic? or should i just swap the tranny to manual and then get the st2

i had a question about the t2 turbo kit...does it come with the st1 turbo but also with the upgraded units? also if i were to go st2...would stock internals be able to handle the boost or does the st2 kit already come with aftermarket internals?

for the st2 kit, whats the highest and safest psi the turbo will handle without blowing up your car because my celica is a daily driver

from wat i understand the st2 is the same parts as the st1 just with a bigger intercooler. then on ur own or thru him you get the internals to handle the extra boost and a boost controller to put the boost up, hence the extra power. anyone correct me if im wrong

bigger intercooler, injector size and boost settings are bigger than stage 1. BUT if you want to boost higher than 6psi (which is stage 1), you have to have internals AND this is where stage 2 happens. Stage 2 is 6-14psi. Stage 3 is with the tranny upgrade and is 14+psi.

Check out www.c2power.com [c2power.com] New updated website!

which one should i get? as some know, i want a stage 3 (can get approximately up to 410hp (Gas did) on 21psi but can go more but that hasn't been tested)...which turbo should i get then? what are the pros and cons of each. I would like fast spool time as well. I do plan on having that much so i want a turbo which could produce this and a little more. Thanks

get the gt28rs. it's a fast spool and you'll get about as much power as the small engine and FWD can handle.

k thanks Don, i appreciate it.

whoa whoa whoa TRDOTC! whats your budget on this project? its looks like you have no problem whipping out the benjamins...haha

so the st2 kit is pretty much st1 but with bigger injector, boost settings, and intercooler right? and what are the other internals i will be needing to be boosting higher psi?

lol, i have some money but i graduate college this may so i will be more strapped when my loan kicks in and i plan on going for my masters but i should be making some good money with a new job and all that crap I plan on getting the small stuff first and then going for the big stuff.

To your questions, this is what Gas and others told me. Yes the stage 2 is just stage 1 with bigger injectors (check monkeywrenching.com for the injector descriptions because they have some points in there that i have to ask C2Power (the difference with the high and low impedence and which one should be used with the Celica) but if you want bigger power, go with 550cc injectors, boost setting with stage 2 is between 6-15 or 16 but safe is up to 14 with the internals, and the intercooler is bigger. If i remember correctly, you can order a lot of this stuff from C2Power and/or monkeywrenching.com.

There are a few things you will need. You will need the low(er) compression pistons from Wiseco (8.8:1), crower rod, you can get the Celica copper head gasket from C2Power which will help keep your engine stable, you can get cams but they haven't been tested with the c2 turbo setup so Gas is testing it soon, he has ordered some, high temp spark plugs, high quality synthetic oil, if you have a GTS, you should get sleeves..can't think of anything else right now but if i do, i will post or someone else will...you already know about clutch and flywheel and the tranny stuff but i think that is all the internal stuff if i am not mistaken.

well i have a GT celica so tell me what i need to get this beast running on st2.

don't forget to replace your stock clutch.

pnoy, he said internals!!! just giving you crap But Gas recommends the ACT X clutch or higher and a lightwheight flywheel. I will get the AEM Underdrive Pulley Kit - Toyota Celica GT, MR2 Spyder (alt only) 00-05...this will work with a turbo, right? If not i won't get it,if it does, i will These are lighter and better looking than stock.

Everything above minus the sleeves is what you need for a GT, i have a GT also

Oh, and with this power, you probably already know but you should get a big break kit (Brembo is the best but expensive and you need at least 16" wheels), and you want all the suspension stuff for better handling (ie Hotchkis TVS)...you know sway bars and all that stuff. Also, don't forget, after the turbo is installed you need your car towed to a place that maps them so you can map it and tune it correctly with the exact gas you are going to use unless the place installing it does it

Well TRDOTC it is well done!

lol, thanks Gas, oh and the info from above is all from C2Power...sorry man, thought i put that the info was from you.

can you bolt on the turbo kits on both automatic and manual transmissions?

pm gas cause i have no clue Hey Gas, i haven't found a 5speed tranny over here..i would lend you mine but i kinda don't have a 2nd car oh, and shipping, no money for that either I'll keep looking...oh and i asked again about the 5speed -->6speed..waiting for anwsers..i hope i can do it because i don't want to lose anything because of the change

k no can do on the info with that post..going to go ask some more wish me luck lol

Yes the turbo can be mounted on both cars. You may need different settings on the auto celi compared to the manual.
If you find a tranny just let me know how much and shipping to florida. Once I could get my hands on a 5 speed I could have a look how modify it to 6 speed with stronger gearset.

k np Gas...florida I thought you were in Hungary?? hehe I'll look around here man, not a problem and I am glad I can help you out since you have helped my ass out a number of times

compared to the TRD supercharger and the C2 turo kit...which is better or more recommened to have?

considering you're in cali, the turbo. you're more likely to find a place to install the turbo than the supercharger. SVLCELI i think has the supercharger. he got it installed and tuned at Monkey Wrench Racing in Detroit. they are very familiar with Toyota engines, so they knew what they were doing. you'd have to e-mail them about what problems they ran into and how tough it was and if they think another shop would be able to do it easily.

My custom kit is set to be put on on april 4th.

I am doing a Precision GT3071R turbo (newer version of the GT30R, it is suppose to spool 1,000 rpm sooner), 420CC injectors, PowerFC, TiAL 38MM BOV, Neukin 40MM wastegate, Neukin turbo manifold, nice sized intercooler, etc.

My buddy makes these manifolds himself and has a lifetime guarente on them.

I'm looking forward to this project!
